Good morning, AI enthusiasts. DeepSeek just pulled off what Western labs refused to do—matching DeepMind's IMO gold performance and releasing it all under Apache 2.0.
While Anthropic and OpenAI keep their best reasoning models locked behind APIs, China's making world-class math AI a commodity anyone can download and use.
In today's recap:
DeepSeek open-sources IMO gold math model
ByteDance video AI crushes Gemini 3 Pro
OpenAI vendor breach exposes API users

DEEPSEEK AI
China's DeepSeek achieves IMO gold
DeepSeek/Screenshot
Recaply: Chinese AI lab DeepSeek just released DeepSeek-Math-V2, an open-source model that achieved gold-level scores on IMO 2025 and near-perfect 118 out of 120 on Putnam 2024 through self-verifiable reasoning.
Key details:
The model uses a novel approach where a proof generator creates mathematical solutions while a separate verifier checks comprehensiveness and rigor, incentivizing the generator to identify and resolve issues before finalizing answers.
DeepSeek-Math-V2 scored gold on both IMO 2025 and CMO 2024 competitions, demonstrating capabilities that match or exceed recent results from Western labs like DeepMind's IMO-Gold system.
The 685B parameter model is built on DeepSeek-V3.2-Exp-Base and focuses on theorem proving rather than just final answer accuracy, addressing limitations in current reasoning approaches that reward correct answers without verifying the logic.
DeepSeek released the model under Apache 2.0 license on Hugging Face, making state-of-the-art mathematical reasoning openly available while Western labs increasingly keep their best models proprietary.
Why it matters: The AI reasoning race just became a legitimately global competition. DeepSeek matching DeepMind's IMO performance while open-sourcing the model shows China's AI labs are no longer playing catch-up. Western companies betting on proprietary advantages in mathematical reasoning now face open alternatives that governments, universities, and competitors can freely use, potentially accelerating the entire field while eroding commercial moats.

OPENAI
OpenAI confirms API data breach
Recaply: OpenAI confirmed that analytics provider Mixpanel was breached on November 9, exposing names, emails, and metadata for API users after an attacker gained unauthorized access to Mixpanel's systems.
Key details:
The breach affected user profile information from platform.openai.com, including names, email addresses, approximate location data based on browser, operating system and browser details, and organization or user IDs.
No chat content, API requests, prompts, responses, passwords, API keys, payment information, or government IDs were compromised in the incident.
OpenAI terminated its relationship with Mixpanel after reviewing the incident and is conducting expanded security reviews across its entire vendor ecosystem.
The company began notifying impacted organizations, admins, and users directly on November 26, warning them to remain vigilant for phishing attempts using the exposed information.
Why it matters: Third-party vendor breaches are becoming the AI industry's Achilles heel. OpenAI's systems were not compromised, yet user data leaked anyway through an analytics partner most customers did not know existed. The company's response, terminating Mixpanel and reviewing all vendors, signals a broader reckoning with supply chain security that every AI company will face as they scale.
BYTEDANCE
AI video editor beats Google and OpenAI
ByteDance
Recaply: ByteDance just released Vidi2, a 12 billion parameter video AI that outperforms Gemini 3 Pro and GPT-5 in spatio-temporal grounding, achieving state-of-the-art video comprehension on videos up to 30 minutes long.
Key details:
Vidi2 introduces end-to-end spatio-temporal grounding that identifies both temporal segments and spatial locations of objects within frames, surpassing Gemini 3 Pro by 27.96 percentage points on vIoU across the VUE-STG benchmark.
The model handles videos from 10 seconds to 30 minutes with 32.57 percent vIoU overall, compared to Gemini 3 Pro's 4.61 percent and GPT-5's 5.47 percent on identical evaluation tasks.
ByteDance built Vidi2 on Gemma-3 architecture with adaptive token compression, processing text, visual, and audio modalities jointly while treating single images as one-second silent videos for unified encoding.
The model extends capabilities to video question answering and performs competitively with Qwen2.5-VL-7B on LVBench and LongVideoBench, marking progress toward comprehensive video foundation models.
Why it matters: China's AI labs are no longer playing catch-up in video understanding. ByteDance beating Google's Gemini 3 Pro by nearly 28 points on spatial grounding shows Chinese models now lead in specific domains despite smaller scale (12B vs Gemini's undisclosed larger size). Western companies banking on video AI advantages face serious competition, and the performance gap suggests fundamental architectural differences rather than just compute scale.
